Read what keepers observed, what authors recommend, and where the evidence leaves questions open.
Keeper reports are attributed experiences. They do not establish species identity, independent replication, biological causes or a guaranteed breeding method. Trade labels and missing measurements remain unresolved.

Coverage and gaps
This is a growing index of selected public sources. Shared authors, copied pages and overlapping cohorts do not count as independent corroboration. Date, unit, taxon, denominator and endpoint gaps remain visible in the reports.
Human-origin judgments rely on attribution and source evidence; no reliable AI detector is claimed. This library republishes original limited summaries and attribution, with no publisher full text or media.
